Did you know poor duct cleaning Toronto of the HAVC system can lead to re-contamination? Well, it can. When some parts of your ventilation system are left uncleaned, they spread dirt to the clean parts, making the entire process a waste of time and money.

So, according to Comfort Clean, when you embark on the cleaning project of your ductwork, it’s worth making sure you know the details of how your contractors are going to work on your system. According to the duct cleaning Toronto requirements by the certification body, NADCA, these components must be cleaned:

• Air ducts
• Coils
• Drain pans
• Registers
• Grills
• Air plenum
• Blower motor and assembly
• Heat exchanger
• Air filter
• Air cleaner

After understanding the components of your HAVC system and those that a cleaning contractor includes on their cleaning work, look into the key components. They are:

Breaking the contaminants loose

Duct cleaning professionals start with identifying the sources of contaminants in your HAVC system. After that, they use agitation devices such as brushes, compressed air nozzles and air whips to loosen these contaminants. Additionally, the technicians can use contact vacuuming or hand brushing for agitation.

Collection of contaminants

Technicians use negative pressure when cleaning your HAVC system so they do not spread contaminants. A vacuum is used in the process. Contaminants are loosened into airborne particles when negative pressure is applied.

The collective device is tightly sealed to ensure that these particles do not escape into the air after cleaning is thorough and the HAVC system switched on.

System access

System access is when the cleaner wants to see the inside part of your ductwork. It can be done through existing openings such as return grills, existing service openings and such. When these openings are used, system access is a simple process.

However, when system access has to be created by the cleaning technician, specialised skill is required. It helps in preventing damaging your ductwork.

Equipment requirement

NADCA certified professionals can use a range of duct cleaning Toronto equipment, varying from moveable to those mounted on a truck. These professionals focus on cleaning without causing re-contamination.

Antimicrobial chemicals

These are products that cleaning technicians use in handling contaminations caused by microbes. Additionally, they help in dealing with odours in your ductwork. They include disinfectants, sanitisers and deodorisers.

However, technicians do not use these products on all occasions. They consider using them after mechanical cleaning is complete and there is a necessity for such treatments.

The duct cleaning Toronto process

• The cleaning technicians zone the supply and return side of the HAVC system so they can clean them separately.
• An access point is created on the supply side so the vacuum can be connected for duct cleaning.
• Negative pressure is maximised by closing all supply registers. At this point, the cleaning professionals work on one duct at a time, dislodging dust and debris using a viper whip system.
• After cleaning all the ducts, the plenum drops and primary trunks are cleaned. High-pressure air is used in cleaning these.
• Then, the technicians turn to the return side of the HAVC system. The same process used in the supply side is used to create an access point.
• A viper whip is used to clean the return ducts individually. The viper whip is snaked approximately 20 feet. and more to dislodge debris and dust from the main trucks.
• When the supply and return sides have been completely cleaned, the technicians use sanitisers for sterilising the system if there is a need for using them. It helps in getting rid of microbes which can re-contaminate the entire system.
• For a thorough job, other parts that are often neglected are cleaned. They include the blower motor, furnace and squirrel cage.
• Once complete, the cleaning professionals start working on sealing the access points. A high-quality sheet metal is used in sealing these holes to prevent leaks. These points can be used later if your HAVC system needs another cleaning.
• The final step includes an inspection of the system to determine whether there are places that have not been cleaned. When satisfied, the cleaning professionals assemble their stuff and leave your premises.

If you have no idea where to find a cleaning professional for the work, you can check in NADCA’s online directory in your area. It provides a list of certified cleaners and you can choose from there.
